I just put up my book review of The Fourth Turning on the Writer's Read weblog.
It's a really fine weblog with about 20 writers regularly reviewing whatever's on their bedside table. Be sure to skim some of the other reviews there.
Also, for your convenience, here's an index to the Fourth Turning posts and supplemental articles:
